September. Despite the ominous foreboding of cold winter months and little income from our solar panels, September was still a very positive month for solar power generation. Not even the wasp invasion could spoil that!

At the end of May, I reported that out meter read 7693 kilowatt hours in what was our strongest solar power generating month yet. Last night, after the sun went down (OK, technically it was this morning – a few minutes after midnight), it read 9661. So we generated 1968 kilowatt hours – just five…
